Sushi and disco. This is what this place is all about. Listen to 80s music while dining. There's a silver disco ball and strobe lights-- I kid you not, but no dance floor. A bit on the cheesy side for my liking, but it's a fun although loud place to get some decent Japanese food.
The spider rolls were good, but the sushi rice was a bit too soft and sticky for my taste. Highly recommend getting the unagi entree though. The eel was fantastic-- just the right tenderness and sweetness, and the portion was so large we took home the leftovers for lunch the next day.
A bit on the pricey side, but a good place to start off the evening if you're planning on going out (i.e. frat hopping) on the Upper West Side.
